Abstract

A straightforward approach to provide protection against packetlosses due to network outages with a longest duration of T time unitsis to duplicate the original packets and send each copy separated intime by at least T time units. This approach is commonly referred toas "time-shifted redundancy", "temporal redundancy", or simply"delayed duplication". This document defines an attribute toindicate the presence of temporally redundant media streams and theduplication delay in the Session Description Protocol.
